Propella 9S Pro: Specs

The Propella 9S Pro is the newest offering in the Propella lineup. It sits just atop the Propella 7S, a bike we reviewed positively for its low price, light weight, fun ride, and strong pedal assist. 

The 9S Pro ups the ante on power with the company’s Pro battery (rather than the Standard on the 7S). The 9S Pro also offers assist up to 20 MPH, rather than the 7S’s 18.5 MPH max assist level. And, as the name suggests, the 9S Pro has nine speeds on its Shimano drivetrain, rather than the 7 speeds available on the 7S.
